BLOW-TQRGH.

To all fwzomz't may concern.'

Be it known that I,4 LOUIS J. CLOUTIER, la citizen of the United States, residing at Providence, in the county of Providence and Statev of Rhode Island, have invented certainnew and useful Improvements in Blow- Torches, of which the following is a speciiication.

.My invention relates'to blow torches ernployed by plumbers, electricians, jewelers and others for soldering or brazing purposes. In these structures are two adjacent compartments one of which supports of the wick and is supplied with a fuel which is directed through the blow pipe upon the iame of the wick to enhance theheat of the iiame.-

The objects of my invention are essentially to afford in a single structure means for supplying at will either-an air current solely 'through Athe blow pipe, an inflammable vapor current solely, any desired mixture of oxygen and vapor, or to entirely cut off the supply of both to the flame; also to protect the operator from any accidental inhalation from the blow pipe ot any vapor.

A further object is to provide a self ignitingr means for the wick which will dispense with the necessity of use ot matches or any other lighting' agent; also to arrange the combined parts in such a manner as to accupy a minimum of space. And finally it is purposed to attain these ends in a vsimple and inexpensive structure.

Toithe above ends essentially my invention consists in such parts and such combinations of parts as fall within the scope of the appended claims.

In the accompanying drawings which form a partof this specifications-Figures land 2 are front and plan elevations rcspectively of my novel torch, the lflexible 5 blow pipe being omitted in Fig. 2, I1`ig.3,a

section on line avec' of Fig. 2, Fig. 4, an end elevation of the torch, Fig.- 5, a detailed partially sectional view of the check valve, and Figs. 6, 7, and 8, enlarged sections of the blowv pipe valve in different positions of operation.

Like reference characters indicate like parts throughout the views.

In detail my device consists of a casing comprising two compartments which may he arranged adjacent each otherin any pre- Speciication of Letters Patent. Application ined February 27, 19135 port-ion ofthe receptacle .B

ferred desired manner andf may be of "any preferred contour. In the present instance the easing comprises two receptacles A. andl bular form .inelosing respectively b, and rigidly connected otherwise as retracted upper portions, and the receptacle A is provided with a neck portion D. In the present instance the neck portion con'- sists of a tube Z provided intermediate its length vwith an external annular shoulder df and. at its lower end with a threaded portion Z2 adapted to-'engagein a thread orifice ala. in a shoulder portion (it constituting a part ofthe upper portion of the receptacle.

such as alcohol e or with an absorbent material containing an infiammalole agent adapted to supply the wick with fuel.

is provided with a retracted portion f provided with external threads adapted to engage internal threads f2 upon the downwardly extended flange portion f3 of a valvecasing F. The valve casing has a cylindrical bore or seat lg and a cylindrical valve seat f'/ by a projecting handle g; The valve comprises a diametrical opening or passage g2 and a second passage 1(1i parallel with the first and open at the periphery of the valve. Integral with the upper extremity of t-he valve casing is an inclined blow pipe tube or nozzle II directed across the top of the neck portion Dot' the receptacle A, in such a manner that any current directed through the nozzle will intersect a flame upon the wick E. Integral with casing F is a downwardly inclined tube or pipe 'Iiprovided at its lower end with an enlarged portion z' which is retracted near its extremity as at 2 to form a valve seat an aperture 3 in its lower extremity.A Resting by gravity in the seat 2 is a hall valve J, shown in detail in Fig. 5, which is of greater diameter than the opening i and the interior diameter of the tube I, but is of less diameter than the breadth of the enlarged portieri i ofithe tube, so that when the ball is lifted it will move upwardly and unseat itseliE to permit the passage of air upwardly through the opening but is checked against excessive upward travel by a transverse pin y' fixed in Patented Nov. d, llil,

hcse receptacles are provided with G rotatable in itsthe side of the valve .no n the present instance the tube O carries l any preferred construction of agent may be 'an After the wick E is lighted the operatormediate degree of heat intensity is desired the vapor and oxygen are mixed. When the device is not in use it is preferable that none of the contents of the chamber b escape. ln order to secure lthe changes in character of the discharge from the tubev H the valve Gis operated. When adischarge of inflammable vapor is sought the air passes through the pipes K and l, the passage Z3, the valve passage g3, the passage E, the tube L, and upwardly through the passages Z2, 2, and the tube H, all as shown in Fig'. 3. When however a blast ofair only is desired the operator while still blowing through the mouthpiece gives a slight turn to the valve handle g, turning the valve to an inclined position, and, as shown in Fig. 6, the passage Z is cut olf thus discontinuing the supply of inflammable fuel, and the passage of the air is through the passages Z3, g3 and the tube H. -When a n mixture or" vapor or air is desired the valve Gr is still further turned to the position shown in Fig. 7. ln Fig. 8 is shown the position of the valve cutting 0E all coin- 90 inunication of the tube H from either the air passage l or vapor passage Z2. Thus, by turning the valve G slightly to various degrees of rotation the force of the current upon the flame, and the vaiious degrees of heat 0f the flame can be perfectly and instantaneously controlled during the process offapplying the flame to the work.

The return of the check valve J by gravthe upper portion of the enlarged part t'. The valve is sliop'n in the last describe position in broken lines in Fig. 5. A ilexilole section of rubber or other suitable ma- 5 terial lll frictionally engages the enlarged portion i' of the metal portion l of the complete or supply tube; and fixed .in the 'end of the flexible member K is the usual mouthpiece 7c. lntegral with or fixed in the bot- 10 toni portion of the valve casing F is a depending tube L which extends nearly to the bottom of the chamber l) which is supplied with ahydro-carbon or other fuel Z which fuel may be absorbed in waste or similar l5 material. A vertical passage Z connects the tube L with the peripheral groove or passage g3 of the valve Gr; and a parallel pasi sage Z2 extends from the lower.l face of the valve casing F to the seat g of the valve.

20 A passage Z3 in the valve casing l? extends from the seatV` g'iintc the tube l. Rotatably mounted upon the neck l) of the receptacle A is a flat ring M located intermediate the shoulder CZ of the tube d' 25 and the shoulder d* of the receptacle, and integral with an upwardly and outwardly directed arm N upon whose outer end is fixed a tubular receptacle or casing O of a -s arising device of any desired construction.

the usual agent consisting of a bar o of pyroplioric alloy in contact with the friction disk F mounted in contact therewith upon a pivot pin p mounted in the ears p upon 35 the upper portion of the tube O. To facilitate the rotation of the disk a hood g has its sides g pivoted upon the pin p. Upon the inner surface of one of 'the sides g are teeth Q2 engagingr the marginal teeth an g3 in the face of the disk l?, so that when the finger projection r integral with the hood q is downwardly pressed the interengagiiig teeth serve to rotate the disk P.- Obviously the hood g may be omitted, and

halation by the operator of any vapor while the valve Gr is in position to permit the operation of the device with vapor. The pivotal. character of the ring M ,and

the arm N supporting,r the sparking` device permits the latter to be swung around when not in use in the path shown in broken lines in Fig. 2 whereby it is brought into a position approximately intermediate the tubes D and H, thereby rendering the entire device much more compact. A rotation of the disk P- as already suggested iinpels a spark to the wick ld and thus produces the llame.

What l claim is temployed upon-the arm N, it being essen` tial only that the sparking disk shall be lo- Acated in proximity with the wick E.

The operation of my device is as follows.

receptacle and a wick therein, of a second receptacle connected with the first receptacle, a valve casing upon the second receptacle, a valve mounted in the valve casing, a blow pipe nozzle upon the valve casing communieating with the valve and directed over the wick, and an air inlet tube upon the valve casing said valve serving` to control the flow of air and vapor.

At other times it is essential that the llame be raised to an exceedingly high temperature, and then it is essential that the current directed against the llame sa be the inammable vapor.
